Only the boot-device driver need be compiled in - the rest ALL
can be loaded - especially if an initrd image is used.
The CD drivers can be compiled as modules with the foll. in

/etc/modutils/actions
# for IDE CD-Writer AND a IDE CD-R
pre-install sg          modprobe ide-scsi
pre-install sr_mod      modprobe ide-scsi
pre-install ide-scsi    modprobe ide-cd

and in /etc/modutils/aliases
# CD-Writer aliases - will ignore hdd as candidate for ide-cd
options ide-cd  ignore=hdd          # CD-Writer on IDE-2 Slave

and if you have devfs, 

in /etc/modutils/1devfsd
# All CD-ROMs
probeall  /dev/cdroms       sg sr_mod ide-probe-mod ide-cd cdrom
alias     /dev/cdroms/*     /dev/cdroms
alias     /dev/cdrom        /dev/cdroms

You have to 'update-modules' after making changes in /etc/modutils
files.

With Debian, you can keep seperate files for say - sound, disks, video.
All files in modutils directory will be merged into
/etc/modules.conf by 'update-modules'. See 'man run-parts' for filename
restrictions.

I use this sort of set-up on Ultra5 and i386 with bare-minimum
compiled-in drivers.

Hope this is useful.
